ABSTRACT Experience with Ropivacaine is still limited, although toxicity studies suggest that ropivacaine has the best safety profile of all local anesthetics. Objective: To determine the anesthetic effects between ropivacaine and bupivacaine in patients for regional anesthesia in the Central Military Hospital during August to January 2013-2014. Design: Prospective, analytical and cross, were performed on 41 patients between 20 and 60 years, ASA I and II, elected for brachial plexus regional block, divided into two study groups. Method: was administered between 75 to 90 mg of anesthetic with a volume between 15 to 20 mi; Group I: ropivacaina 0.596 or 0.496. Group II: 0.596 bupivacaine, usingneurostimulator for brachial plexus block as art. Sensory and motor block, máximum latency, time in both, time reversal of motor and sensory block, analgesic effect, patient satisfaction and incidence of adverse effects. A datábase in Microsoft Excel format and the data were processed and analyzed with SPSS. Results: There were no significant dif-ferences in demographic variables. Again latency but a difference in relation to the engine block and the duration of analgesia quality anesthesia. The onset of motor block was faster with bupivacaine, but was greater duration of sensory block, motor and analgesic time with ropivacaine. Conclusions: A dose of 75mg and 90mg, 0.5 to 0.496 concentrations of ropivacaine allowed us to perform a quality comparable to that lock is made with 50mg bupivacaine 0.2596 in contrast to the ropivacaine provides a good sensory block and less motor, intra-and postoperative analgesia was good.
